(2, 4+ C Indian River County, Florida Department of Utility Services Board Memorandum Date: February 7, 2020 To: Jason E. Brown, County Administrator From: Vincent Burke, PE, Director of Utility Services Subject: CR -510 Utility Design Agreement a.k.a. Utility Design by FDOT Consultant Agreement Background/Analysis: The Florida Department of Transportation (FDOT) has plans to widen County Road 510 (CR -510) beginning at CR -512 to 58th Avenue. The approximately 5.22 miles of existing two lane roadway will be widened to a four -lane roadway divided with curb and gutter. The proposed roadway improvements will include drainage structures in the form of curb inlets approximately every 500 linear feet. The Indian River County Department of Utility Services (IRCDUS) owns and operates two large water and wastewater mains within the existing CR -510 right-of-way (ROW). Specifically, there is a 12 -inch PVC force main along the south side and a 16 -inch water main along the north side of CR -510. The force main conveys domestic wastewater from multiple locations including Sebastian River High School, Treasure.Coast Elementary, parts of Sebastian and flows generated within the City of Fellsmere. The water main provides potable water to these same locations including Vero Lake Estates, provides looped water service and is a major transmission main used for fire flow purposes. Initially, staff considered offsetting portions of the force main and water main to avoid the proposed drainage structures needed for the four -lane roadway improvements. However, the 56 proposed offsets of 12" and 16" lines highlighted the fact that the time and effort needed to provide the infrastructure offsets was not cost effective. Secondly, due to the new roadway alignment, the existing water and force mains, which are now in the ROW, would be under the new pavement sections. Getting to any future repairs could be costly and arduous if staff had to open -cut new sections of the roadway. Third, the water main and force main are 28 and 19 years old, respectively. While not past their useful life, the lines are not as new as would be expected, and potential breaks under new roadway sections could be a liability for IRCDUS. Having multiple offsets to accommodate drainage pipe led staff to consider the cost effectiveness of keeping the existing pipe, and whether we would be comfortable with these main lines under asphalt. Lastly, keeping the existing lines in service during a major roadway project presents its own challenges. For the reasons mentioned above, staff began negotiations with FDOT and their utility design consultant, Snubbs Consulting, Inc. (Snubbs), in 2019. IRCDUS initially thought it would be most cost effective to hire a professional engineering services firm under our continuing consultant agreement. However, keep in mind that, per Florida Statute 287.055, the firm's design fees cannot exceed $200,000, or the cost of construction cannot exceed $2 million. This project would exceed both of these thresholds. Next, a Request for Qualification (RFQ) process was contemplated, but the four to six months needed to obtain a firm would put IRCDUS in .a tight timeline with FDOT's project schedule. They would need fully 119
